Hey @Cleiton Santos Racheal from the support engineer team here 

At the moment, Intercom does not support the ability to disable the start a new conversation button based on hours, but I totally understand where you're coming from here and think you should have more control and flexibility here. I would love to pass this along as a feature request for the product team. If there are additional workflows or context not mentioned above, I'd be happy to include them in my notes to the team!

Regarding your second question, can you clarify what you mean by activate it? I’ll attach a helpful Article here detailing what is possible with our native WhatsApp integration:

Hi there!

Great question! Intercom absolutely lets you customize chat availability, like setting it from 9:00 AM to 6:00 PM on weekdays, and automatically switches to tickets outside those hours. It’s a seamless way to manage customer expectations while keeping support efficient.

For WhatsApp, yes! Once you link your business account, you can add it as a messaging channel in Intercom, making it easy to connect with customers where they already are.

Think of it like a well-run school: just as a reliable cleaning service keeps classrooms tidy for better learning, Intercom’s tools keep customer conversations smooth and organized.

Need help setting it up? Intercom’s guides walk you through it step by step. Hope this gets you started—you’ve got this!

Hi Cleiton!

Intercom does offer the flexibility to set your chat availability based on your business hours. For example, you can schedule your team to be available from 9:00 am to 6:00 pm, Monday through Friday. Outside of these hours, chats can automatically switch to tickets or display an away message, helping to set clear expectations. As for WhatsApp, Intercom’s integration allows you to connect and communicate with contacts, provided you have access to the WhatsApp Business API.

If you're in the healthcare field, keeping communication clear is as essential as keeping your space clean. For medical offices in Austin, services like this ensure your facility stays spotless and infection-free. Let me know if you’d like help with setup!
